Figure 5 is a detail view, to be hereinafter referred to.

Similar letters of reference indicate lilce parts.

This invention relates to a machine on which a circular saw, a reciprocating saw, and a chisel can be arranged in such a manner that all work which can be performed by the `:said instruments can be done on the machine by hand or other power. The invention consists in the mode of applying and regulating the power by which the machine is driven, so that the latter may be used for light and heavy work, as may be desired. The invention also consists in an automatic feed-motion, in the manner of securing and adjusting the bed for mortising, and finally, in the device for holding the reciprocating saw, wherein the chisel for mortising may also be secured.

A represents an oblong frame, made of wood or other suitable material, and supported upon pillars B, as shown in thc drawings. C is a transverse horizontal shaft, mounted in suitable bearings in the frame A, and provided at onecnd vwitha pinion, a, and crankb, as is clearly shown in figs. 1 and 2. D is another transverse shaft arranged on the fratrie A, and provided at one end w'itli a toothed wheel, c, which meshes into the pinion a, as shown. A crank, cZ, is also-'attached' to the end of the shaft D. A circular saw, E, is mounted on the shaft C, and when the same is to be used a stationary bed is arranged on the top of the frame A, and the machine is yfed by hand or. by suitable machinery as now in use in machine sawinfr. Between two Slotted upright-s, F F, which are stationary, arranged at the sides of .the frame A, is held the vertical reciprocating saw-frame G, to

the side of the saw-frame, and their lower ends secured eocentricallyitoa transverse shaft, H, on which a pinion, g, is mounted that meshes into the cog-wheel c on shaft D. Thus, as either the shaft C or D is revolved, motionl is imparted to the shaft Il and to the said frame G, the latter moving up and down, guided by the slotteduprights AF. By applying power to the shaft C a slow motion is given to the saw-frame, while, when quick motion is required, the power is 'applied directly to the shaft D. The uprights F F are connected on top by a cross-bar, k, on which bearings are arranged for an oscillating shaft, z'. The caps on these bearings are' hinged or otherwise attached', so that the shaft can be easily removed if desired. An arm, j, projects at right angles from the outer end of thel shaft 2f, and is iirmly secured to the latter. The arm j-isconnectcd by a rod, K, to the end of a y-lever, I, secured to one end of the shaft C, as shown. The leverI is slotted, and the rod K is attached toit 'by a pin passing through theslot and heldinplace by a nut, whereby the distanegof the lower end of the rod K'from the lcentre of the shaft C cnn be regulated. To the inner end ofl the shaft is secured at righta angles an arm, Z, the end of which is connected by a rod, m, with'a plate, fn, which is secured to a crossbar, 0, ofthe sa\v-frame G'. By revolving the shaft C the shaft is oscillatcd, and by its connections m and n with the saw-frame the latter is moved up and down. If desired, the gear-wheels a, c, and g, and the system of levers above described, may be employed at the same time for moving the saw-frame `up and down, or either of them alone. To use the gear-Wheels alone, the shaft i can be taken ofi', ori-account of the open vbeariugsn To use thc lever motion alone it will be necessary to move the shaft H in its bearings, so as to throw the pinion g out of gear, thereby rendering it necessary to move the rods e e on the pins ff, and to secure them so that the rods a will bc vertical .on the shaft H. The upper ends ofthe rods 'e are secured by small keys or Iscrews to the pins f, which are provided with two holes c ach, to receive the` keys or screws, so as to allow for the shifting of the rods c. The shaft II is shown out of `gear in iig. 4. lVhen the' pinion g is inp-gear, the shaft'I-I is-prevcnted from shifting of its own accord by a pivl'ted clamp p, (shown `in fig. 1,) or by some other` stop, arranged on the side of the upright I", opposite lto that on-which the pinion g is'arranged. The rod K is provided with ahandle., g, whereby one hand ofthe operator may be used to pull directly on the said rod while the othertu'rns the crank on the shaft D. This handle q, as well as the fly-lever I, serves greatlyto increase .the power-of the driving mechanism. The lever I has been found to do better service than a ily-wheel, especially when its free end, z. c, that to which the rod K is not attached, is arranged so as to swing downwards when the saw-frame descends. The saw-frame consists of two cross-bars on which slotted arms, Ii, may bevarrangod, to the front end of which the saw L is attached, as shown in lig. 1. Said slotted arms are so arranged that the saw can be set at a greater 01 less distance from the saw-frame. They have been-fully described in the Letters Patent granted to 'me on the eighteenth day of December, 1866. The saw L may also be secured directly between the cross-bars of the saw-frame, as is indicated by red lines in figs. 3 and 4. In that ease its uppcr'end is inserted in aislot provided in the under surface of a block,7', which is secured to the uppereross-bar 'of the saw-frame, as shown, and is held in place by a pin,v s, as shown more particularly in g. 5, which is an inverted View of the block t'. The slot in the latter for holding the saw is widened 'in the centre, so as to form a hole, in which the mortising chisel M (the operations of which will be hereafter described) isinserted, and is also held by the pin s. When the reciprocating saw L is used, a slotted carriage, N, is placed upon the frame A, being provided with rollers t at its under side, as shown, so as to slide easily backwards and forward on the framcA, the saw L passing through the slot. A ratchet-bar, w, is secured to the carriage, as shown in gs. 1, 2, and 4. Acurved arm or lever, O, is hinged to a crank on the oscillating shaft z', which is so arranged. that its forward `curved part is heavier than its lower end, so that 'the latter will be elevated above the carriage N, as shown by red lines' in iig. 1. A weight, t', can be\secured by means of screws to the lower end of the lever O, and then the same will be held down upon the ratchet-bar w, as shown. By the motion of the shaft t' the lower end of thelever O is moved back and forth, and while moving backiit carries the carriage N along, and thus feeds the wood that may be placed thereon to the saw. When no feed is required the weight 'v is removed, and then the lever O will not come in contact with the ratchet. Thus the reciprocating saw can be used with or without an `autoniiatic feed, can be made to work with more or less power by the use of the gear-wheels and lever arrangements, and with more or less speed, and can be removed altogether, so that the circular saw or the chisel may be used, as may be desired. When mortising is to be done, the saw L is removed and the chisel M is secured in the block r and held in place bythe pin s in the manner above described, and as shown in figs. 3, 4, and 5. rIhe carriage N is removed from the frame A, and the weight v is removed'from the end of the lever O. A bed, P, consisting of a wooden plate provided with slotted supports Q, is placed below the chisel, the supports resting upon the wedgeshaped block R in such a manner that by moving the said block forward or backward thc bed P can be raised or lowered, andas it is provided with pins at its ends which t around the sides of the uprights F, the said bed will always retain its properposition, no matter how much itlmay be raised or lowered. A pin, w, is inserted in one of a series of holes,y which are provided in the block It, so as to come in contact with thatedge of the support Q which reachesito the lower part of the block, thus preventing theblock R from sliding outf'rom under'the supports Q, which`,"au'd the bed I), are irmly secured in position by a bolt, S, passing through the slot in the supports, and through a cross-bar, T, arranged vbetween the uprights F, as clearly shown in g. 3. '.lheY head VVof the bolt S, and thenut z by which the bolt is held secure, prevent longitudinal motion of the bed I. The uprightsnF, between which the latter securely ts, prevent lateral motion of the same, while the bolt S prevents vertical motion.l By loosening the nut z and removing thc pin w, the bed P can be raised or lowered by adjusting the wedge-shapcd block, and the bed is then again secured in position by reinscrting the pin w and tightening the nut z. The chisel can now be operated by the same mechanism by which tlie'rcciprocating saw is moved, and any suitable sort of mortises'may thus he formed on this machine.

What I claim as new, aud desire to secure by Letters Patent, is-f- The arrangement of the lever m, plate n, shaft z', levers j,7c, and I, by which motion is imparted from the shaft C to the reciprocating frame G, as herein set forth, for the purpose specified.
